Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| macos:unifiedlog | Outbound Traffic | DC0082 Network Connection Creation |
| macos:osquery | Process Execution + Hash | DC0034 Process Metadata |
| NSM:Content | HTTP Header Metadata | DC0085 Network Traffic Content |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
ParentProcessFilter | Limit detections to children of suspicious binaries. |
HeaderAnomalyScore | Threshold for deviation from expected headers (User-Agent, Host). |
